Blockstream app mobile and desktop bitcoin wallet

Swiss angle

The Blockstream app comes from the United States, not Switzerland. The Blockstream terms of use, read on 4 October 2026, name Blockstream Corporation and say it offers its services from facilities in the United States of America, under California law. The app is a self-custody wallet: your keys sit on your phone or computer. Even in a 2FA account Blockstream holds only a second key, and the help article on 2FA says a send needs both keys. Blockstream cannot move your coins alone, so the app is not a financial service account.

You can set the menus to three national languages. The app page lists French, German and Italian among the supported languages, next to English and ten others.

You hold the keys, so no bank sends you a year-end statement. At year end you look up the ESTV value of your coins and declare it in the wealth tax section of your return; the Swiss Bitcoin tax guide explains how. We found no Swiss office, franc price or Swiss support line on any Blockstream page we fetched.

The name changed. The Blockstream help centre calls it the Blockstream app (formerly Blockstream Green), so older guides still say Green.

Who it is for

People who want one wallet on phone and computer. The app page offers downloads for iOS, Android, F-Droid, Windows, macOS and Linux, and says the app is 100% open-source software.

Users who care about privacy. The same app page says you need no documents or personal data, and that you can connect to your own node and route traffic through Tor.

Owners of the Jade hardware wallet. The app page says the Blockstream Jade integration keeps your keys in cold storage while you still use the app.

People who want a second key as a safety net. In a 2FA Protected account, once called Multisig Shield, the help article says the first key stays on your device behind a PIN and the second sits on Blockstream's servers behind two-factor authentication. The same article says each deposit gets a timelock of 51,840 blocks, around 360 days by default. After that, your own key can spend it alone. The chapter on wallets and staying secure explains how a second key changes the risk.

Who it is not for

Anyone who may want to move a 2FA account to another app later. The Blockstream app help page says singlesig wallets restore in other BIP39 software such as Electrum. Wallets created with two-factor authentication restore only in the Blockstream app.

People who do not want to manage redeposits. The help article says the app prompts you to redeposit funds before their timelock expires, if you want them to stay under 2FA.

Users who would rather not choose between Blockstream account types. A singlesig wallet in BlueWallet or Electrum keeps every key with you from the start.
